Blue Aadhaar Card: A Comprehensive Guide for Children’s Registration

In India, the Blue Aadhaar card is designed specifically for children under the age of five, serving as a vital Know Your Customer (KYC) document. Issued by the Unique Identification Authority of India (UIDAI), this card plays a crucial role in accessing government subsidies and welfare schemes, featuring essential details like the child’s full name, permanent address, and date of birth.

Biometric Data Requirements for Children

Unlike adults, the issuance of the Blue Aadhaar card for children does not necessitate biometric data initially. Instead, the UID is processed based on demographic information and a facial photograph linked with the UID of their parents. However, when the child reaches the age of five and again at fifteen, biometric data updates for ten fingers, iris scans, and facial photographs become mandatory to maintain the card’s validity. The biometric data update for teenage Aadhaar cardholders is provided free of charge.

In 2018, UIDAI introduced the concept of the ‘Baal Aadhaar’ card, distinguished by its blue color, exclusively for children under five years old.
